Analysis and Design Guidelines for Buildings Subjected to Pounding Based on the Damage Observed from 1989 Loma Prieta Earthquake

这是1989年10月洛马普列塔地震后的一次地震。 调查项目在学习这一破坏性的 活动 这个项目的重点是研究 相邻建筑物相互撞击 根据实际的损坏观察。 调查的目的是：（1）调查的频率和类型 发生的碰撞，（2）分析评估 对几栋建筑物的撞击造成的影响， 观察到的结构损坏的冲击，（3）， 调查撞击的不利影响，以及（4） 为工程师提供指导，以减轻损害 从敲打。 预期研究结果：观察到的总结 由于碰撞造成的损坏，以及对 与实际观察到的碰撞损伤相关， 建筑物的建模过程和设计方法 以及减轻冲击的方法 对现有相邻建筑物的破坏。 这项研究将有助于更好地了解 现象和减轻损害的适当途径 与冲击的联系。

This is a post Loma Prieta earthquake (Oct. 1989) investigation project in learning from this damaging event. The focus of this project is to study the effects of pounding of adjacent structures against each other based on the actual damage observations. The objectives are: (1) to survey the frequency and types of pounding that occurred, (2) to evaluate analytically the effects of pounding on several buildings that had observed structural damage from pounding, (3) to investigate the adverse effects of pounding, and (4) to provide engineers with guidance to mitigate the damage from pounding. The expected research results: a summary of observed damage due to pounding, and analytical investigation to correlate with actual observed pounding damage, a proposed modeling procedure and a design method for buildings subjected to pounding, and a method of mitigating pounding damage on existing adjacent buildings. This study will lead to a better understanding of the phenomena and proper ways to mitigate the damages in connection with pounding.
